DFC25E24T5 Datasheet, PDF (1/2 Pages) Power-One – TRIPLE OUTPUT
DFC25 SERIES
TRIPLE OUTPUT
DESCRIPTION
The DFC25 Series DC/DC converter provides three output voltages
from a single 12, 24, or 48 volt nominal input for industrial and
datacom equipment. Available output power ranges up to 25 watts.
Excellent noise performance is attained via an aluminum case,
toroidal magnetics, and double shielded transformers. Common
mode and differential mode input filtering are integral to the design.
Selected models provide 1544 volts isolation from input to output.
The input and output sections of the DFC25 Series are protected
from overvoltage transients via internal circuitry. Same voltage
single output units of the DFC25 family may be connected in
parallel to achieve additional output current.
